definetly go cradle mount, hand helds have to small a screen to do any good. if you zoom in to where its legable you loose all the range and zoomed out the screen becomes to crowded. Lawrance iWay is a great all around unit. does land and sea navigation with pre loaded highly detailed maps. also has Xm radio and is FM modulated. got tons of other features and price isnt to bad.Also this is about the smallest screen you would want to go with.
